虎威及其混剂防除大豆田阔叶杂草试验效果初报

Preliminary Report on the Control Effect of Broad-leaved Weeds with Fomesafen and the Mixed Herbicide in Soybean Field

通过田间试验明确了虎威及其混剂对大豆田阔叶杂草的防除效果及对作物的安全性,提出了最佳配方为虎威1.0L/hm2+排草丹1.0L/hm2及虎威0.75L/hm2+排草丹1.5L/hm2。可以扩大杀草谱和提高对作物的安全性,为更好的防除大豆田阔叶杂草提出依据。

According to the field trail on the safety of Fomesafen and the mixed herbicide to the soybean and the control effect to broad leaf weed in soybean field, the usage of Fomesafen 1.0L/hm^2＋ 1.0L/hm^2 and Fomesafen 0.75 L/hm^2＋ Bentazone 1.SL/hm^2 provide the best control. It not only expand the weed control range but also improve the safety standard to the soybean. The study provided evidence to control the broad leaf weed more efficiently in the soybean field.
